Safe direction-finding is extremely necessary for multihop wireless systems such as Wireless Sensor Networks. Multihop wireless systems are more defenseless to safety outbreaks as associated to single stage wireless networks. Cross layer design production a precise significant character for wireless sensor network submissions. Advanced security is actual significant for the achievement of announcement among sensor nodes in wireless sensor network because the numbers composed is regularly slight and the network is mostly susceptible. Numerous Security methods have been suggested to deliver safety resolutions beside numerous extortions to the Cross-layer modification techniques in Wireless sensor network. In this paper we overview the existing schemes for the security of cross-layer design in wireless sensor network. Proposed Security model will provide more security between sensor nodes and base station in wireless sensor network. Security is important for the success of the wireless sensor network because the data collected are often sensitive and the network is particularly vulnerable. In the cross-layer design, constraints are substituted between changed layers to protection well-organized use of energy. In this paper, we propose a secure security model that is based on cross layer design. It uses a cross layer optimization Mechanism. Reproduction consequences confirmation that our proposed safety model can achieve better in many situations and in unfriendly violence-disposed to situation.
